In .some types ohmic-functional window assemblies where the transversely arranged bars function-both as detentionbars and as'muntin bars, difficulties have been encountered in :se-

curing the .necessary cheapness .of construction,

'ciency of the window assembly. This is further complicated whenproviding adequate protection across the more vulnerable area, that is, across the ventilating area.

In the present modification the vertical muntin bars It! constitute eye bars having openings or eyes 42 longitudinally disposed with respect to the web of the vertical bars H3. These vertical bars) may be T-shaped in cross sectional area. As the side bars M- are embedded in the masonry, these bars need not necessarily be T-bars; but may have oppositely disposed flanges 1'6 and 18, the former receiving the glazing 2i) and the latter embedded in the masonry. The bars 1'5 may, however, be provided with eyes or openings similar to and aligned with the openings T2 in the webs of the bars 10.

The horizontal muntin bars '22 constitute the needle bars and may be T-shaped in cross sectional area, the'stem of the T being provided with a downwardly projecting "flange 24 at the end thereof, to give'rigidity to the bar. These horizontal bars 22 may have the flanges cut away as shown at 28, so that as the needle bars 22 are passed through the openings [2 in the :muntin bars H3 and rotated through '90", the cut away portionzfl of the bar '22 overlaps the flange of the bar Ill. Likewise, the cut away portion 26 may overlap the enlarged rib'30'of the eye bar ll.

Rectangular duo-functional key and detention bars 32 are then passed through the enlarged portion of the opening I2, so as to prevent rotation of the needle bar and hold it in position;

thereby preventing the displacement of this bar. The cross sectional area of the duo functional detention and key bars is sufiiciently large to snugly rfit into the portion of the openings 12 extending beyond the uncut web'portion of the needle bars 22.

The key bars in the modification shown extend horizontally in close spaced relation and preferably'on the under side of the muntin bar 22. The key bars 32 may be of tool resistingimaterial so as to deter the severing of the horizontal bars, therebyfunctioning as detention bars. The tool resisting muntin bars 32 however, do .not deter or prevent the inmates from cutting the vertical muntin bars It.

By severing these vertical muntin bars it) it may give the inmates a fairly good leverage to twist, bend or deflect the horizontal detention bars, even though these bars are not severed. For institutions used in confining or excluding hard boiled criminals, or others, it mayalso be desirable to provide tool resisting portions aligned withand contiguous tothe vertical bars.

Vertical detention bars of tool resisting material may be used inparallel width andembrace'd by the vertical bars across the ventilating area which may include a group of spaces that are not glazed; but detention bars positioned adjacent to the webs of the muntin bars extending across the glazed portions of the window obstruct the easy glazing thereof. It is preferable to find some other suitable location for the tool resistant detention bars extending across the ventilating area.

In the modification disclosed and best seen in Fig. 4, tool resistant rectangular detention bars 40 extend across the ventilating areas and are placed along the side of the web of the detention bars II). The detention bars 40 prevent the easy cutting of the detention bars l0 across the more vulnerable portion of the window.

A cap member 50 provided with a suitable recess is preferably used to cover the flanges of the muntin bar In extending across the fixed spaces. These cap members prevent the sawing of the muntin bars H]; but do not obstruct the glazing of the fixed spaces, as the cap members 50 are placed on the inside of the glazing. It does, however, prevent the inmates from severing the muntin bar above and below the ventilating area, as this cap member 50 is made from tool resisting material.

Member 50 is provided with extensions 5! overlying the flanges of the transversely disposed muntin bars. In order to accommodate the closure frame, the extension 5! terminating at the ventilating area is provided with a lip 53 that overlaps an outwardly projecting flange 55 of the closure frame 60.

Suitable holes 52 extending through the flanges of the muntin bar I 0 permit the pouring of fused metal so as to weld member 50 to the muntin bar. Both of theflanges are preferably provided with such holes 52, although only one has been shown. Member 50 in the modification disclosed extends from one muntin bar to the adjacent muntin bar. It could, however, extend continuously along the entire face of the flanges of the muntin bar In from the top to the bottom of the window. Likewise, it could extend across the ventilating area by providing clearance therefor or sufficiently offsetting the closure.

In the present instance the closure includes a movable member not shown, pivotally attached to the frame 60 that is mounted upon a sill 64 interlocking the flange of the muntin bar bounding the bottom of the ventilating area. The closure may be any conventional type movably mounted at the bottom, at the top, at' either side or along the center or otherwise.

Referring to the modification disclosed in Figs. 7 to 13 inclusive, the horizontal T-bars [0 have been provided with T-shaped openings 12 terminating in an enlarged portion 14 and the vertical muntin bars 16 have cut away portions 18. The T-shaped openings 12 are sufliciently large to bodily receive the needle bar I6, which is passed through the openings 12 until the cut away portion 18 registers with the proper T-bar, at which time the bar 16 is bodily moved so as to position the flange in alignment with the flanges 82, the flanges 82 being seated in the cutaway portion 18.

When the needle bar 16 has been thus positioned, a duo-functional detention and key bar 84, preferably made of tool resisting material and square in cross sectional area, is passed through the openings 14 in alignment with the web of the T-bar 16 so as to interlock the bars in fixed relation with respect to each other, as shown at the extreme right of Fig. 12.

For this type of construction it is quite desirable that the maximum width of the T-bar 16 be somewhat less than the width of the web of the horizontal bar 10. As the key bars 84 are positioned along the outer edges of the webs of the T -bars 16, sufficient clearance is provided for the insertion of the glazing so that the duofunctional detention and key bars 84 may extend across both the ventilating area and the fixed glazed spaces.

In this modification it is not absolutely necessary in order to provide proper protection across the ventilating area to have the muntin bar extend continuously across both the ventilating area and the fixed glazed spaces. The muntin bars may terminate at the ventilating area. When they do, it might be desirable to provide additional protection for this more vulnerable area.

In the modification disclosed in Figs. 7 and 9, transverse detention bars 86, which may have notches in the side thereof, extend across the ventilating area and are welded to the vertical key bars 84 and to the muntin bars bounding the ventilating area. The transverse detention bars 84, which are preferably of tool-proof material, may also be used to prevent the severing of the muntin bars bounding the ventilating area and the other muntin bars disposed at right angles to the duo-functional detention and key bars 84.

In some structures the horizontal bars 86, or for that matter the vertical bars 84, may be eliminated at the fixed glazed spaces. the horizontal bars or the vertical bars or both may be provided with capping members 50, similar to those which have already been described in connection with the modification disclosed in Figs. 1 to 7 inclusive, and shown in detail in Fig. 3.

The unglazed ventilating area is preferably provided with a closure assembly only the frame of which has been shown, as any suitable movable closure may be used with this frame.

The lips 53 of the cap members 50 overlap The ventilating frame may be inserted much the same as the window panes, namely by inserting the top flange under the lips 5| or the top flange -under member 96 and then shoving the lower flange over the top of the sill 64.

As members 50 and capping member 94 are made from tool resisting material, these deter the severance of the adjacent portions of the muntin bars.

Although the preferred modifications of the device have been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts which generally stated consist in a device capable of carrying out the objects set forth, in the novel parts, combination of parts and mode of operation, as disclosed and defined in the appended claims.
